For each pair of graphs G1 = <V1, E1> and G2 = <V2, E2>
a) determine if they are isomorphic or not.
b) Determine a function that can be isomorphic between them if they are isomorphic. Otherwise you should justify why they are not isomorphic.
c) is there an Euler road or an Euler bike in anyone graph? Is Hamilton available? You should draw if the answer is yes and reason if your answer is no.
Consider if the relationship represented by the directed graph is an equivalence relation.
If a graph G = (V, E), |V | > 1 has N strongly connected components, and an edge E(u, v) is removed, what are the upper and lower bounds on the number of strongly connected components in the resulting graph? Give an example of each boundary case.
